SPECIFICATION mrming'part of Letters Patent No. 739,430, dated September 22,1903.

Application fili'rtvembefzgistz. Serial No.132,616 (No'modeh) I,

To all whom, it may concern:

Be it known that I, EDMUND H. LU-NKEN, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in WVindows, of which the following is a full, clear, and exact descrip-' tion, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to all classes of windows for buildings which have sliding sashes to be raised and lowered in opening and closing the windows and it has for its object, first, the provision of an inclosed casing above the window opening proper to receive the main sliding sash, also the shutters directly behind or outside of said sash, also a burglar-proof grating behind or outside of said shutters, and, finally, screens behind or outside of said burglar-proof grating; second, the novel con-' struction of the parts last enumerated and their arrangement and relation to each other in connection with devices for operating the same, and, third, in the details of construction and arrangement of the parts whereby not only is a very handsome window produced, but one that possesses all the desirable qualifications of being opened for ventilation and of being provided with shutters and a burglar-proof grating, which will add to rather than detract from the appearance of the window, and having screenswhich can be brought into use orraised out of sight when not needed, and, finally, in a provision of the main sash whereby it may be swung inward into the room to permit of the ready cleansing of its outer surface without the necessity or danger of sitting or standing out on the window-sill, asis commonly done, or of opening theflyscreens, and whereby an increased window-opening is secured. The novelty of my invention will be here inafter more fully set forth, and specifically pointed out in the claims.-

In the accompanying drawings, Figure 1, Sheet 1, is an inside elevation, partlyin section, of a residence window embodying my invention. Fig. 2, Sheet 1, is a sectional side elevation on the dotted linem wof Fig. 1 looking to the left. Fig. 3, Sheet 2, is an outside elevation of the window closed and with the burglar-proof grating lowered to protect the window. Fig. 4, Sheet 2, is a view corresponding to Fig. 2 ofthelower part of the window, showing the main sash secured on its hinging-pivots and swung out to give access to its outer surface for cleaning purposes.

Fig. 11, Sheet 4, is a view corresponding toFigs. 2 and 9, showing a slight modification in the construction. Fig. 12, Sheet 4, is a plan view of the box or casing containing the guiding and supporting pulleys for the various ropes. Fig. 13, Sheet 4, is an enlarged elevation, partly in section, of the lower part of the burglar-proof grating and its locking mechanism. Fig. 14, Sheet 4, is an enlarged elevation of one of the rope-guiding pulleys and its hood. tional plan view showing the method of unit;

of the burglar-proof grating and upper sash. Fig. 16, Sheet 4, is a sectional detail plan for the main sash.

The same letters of reference are used to indicate identical parts in'all the figures.

I will now first describe my improved win dow asintended for residences and illustrated in Figs. 1, 2, 3, 4, 10, and 12 in connection with the detail views to be referred to in the description.

In Figs. 1 and 2 the windows are shown in tiers, the one directly above the other, and A represents the flooring separating a }lower room from an upper room, and the Windowframe B is built into the wall withits base or sill O at a convenient distance from the fioor and its top or cornice D near the ceiling. The side walls of the frame extend continuou sly from the upper side of the sill of a lower ing one of the sliding guides to the side bars View, enlarged, of the guides or parting-strips Fig. 5, Sheet 2, is a sectional detail elevation,

Fig. 15, Sheet 4, is an enlarged sec- 1- window through the floor above it and to the under side of the sill of the window in the room above, and each contains a box or well E for the weights and operating-cords. It is my intention to construct these frames entirely of metal, though any other material may be employed without altering the scope of my invention, and the inner walls F of the boxes E contain all the guides for the sliding parts, as seen in Fig. 10. By this construction an inclosed casing or box G is formed between the top or cornice D of a lower window and the under side of the sill O of the window next above, said casing or box G having at its top a supplemental box H with a bottom partition I for the passage of the ropes and for the guidance of thesame over pulleys, as J, suitably journaled to the partition I and covered by hoods K, as seen in Fig. 14.

The main sash L of the window, which is 011 the innermost side of the frame, occupies about three-fourths of the windowopening, and, as seen in Figs. 10 and 115, it is guided between a parting-strip M, on one side, recessed in the walls F, and an inside strip N, which is T- shaped in cross-section and is recessed in the wall F. The inner side of the parting strip M is preferably supplied with a strip of rubber or soft metal a, Fig. 16, recessed therein and bearingagainst the outer side rail of the sash to hold the same against rattling and to exclude air and dust. The strip N extends only a slight distance above the top rail of the sash L when the latter is closed, so that when it is desired to clean the glass of the sash L the strips N on each side can be pushed up above the top rail of'the sash, as seen in Fig. 4, to permit the sash to be raised above the shoulder e in the sills and then drawn out slightly to permit bolts Z), Fig. 5, to be pressed outward into recesses in the window frame and serve as trunnions to permit the entire sash to be swung inward into the room, and thereby enable the outer surface of the glass to be cleaned from the interior of the room, as will be readily understood by reference to Fig. at. hen this cleansing is done, the sash is pushed outward into place against the parting-strip M, and the strip N is drawn down again to serve as the inner guide for the sash when the latter is raised or lowered in the ordinary opening or closing of the window. The sash L is counterbalanced by a single weight 0, Fig. 1, in the left-hand box or well E of the frame. From this weight two ropes c ascend over pulleys J, Fig. 10, in the casing H, and one of them passes over a pulley at (Z, and thence down to the sash L on one side, and the other extends across the box and over a pulley at e and down to the opposite side of the sash. The two ropes c are preferably in one piece with theiropposite ends united to the sash L and passingaround a pulley f upon the upper side of the weight 0, Fig. 1, so as to compensate for any shrinkage of the ropes and to perfectly counterbalance the sash L at all times.

Above the sash L is a smaller sash P, fitting the upper part of the window-opening and with its lower rail and the upper rail of the sash L meeting on a level, as seen at 9, Fig. 2. This sash is only capable of being drawn downward and is guided by strips 71, Figs. 10 and 15, which are fitted into moriises in the outer edges of the side rails of the sash and are locked therein by set-screws 1', while their projecting ends are confined in grooves in the walls F, as seen in Fig. 10. The sash P is counterbalanced by a weight Q, Fig. 1, in the left-hand box or well E, the ropes j of which pass up over the pulleys in the box H, as at and thence pass down to each side of the sash P.

Just outside of the sash P and guided by pins, as in Fig. 7, in the side walls F are two shutters R R, consisting of slatted frames of any suitable construction and rather loosely mounted in their slides, so as to descend'by gravity. These shutters are supported by central ropes which pass up over pulleys, as at m, the ropes n thence passing over to pulleys at 0 and going down in the right-hand box or well E and around a pulley 19, mounted in a weight S, which is connected by a thumbsorew q, Fig. 6, to a slide 1' upon the outer side of the window-frame, as seen in Figs. 1 and 8. The weights and the slides preferably bear against the front face 3 of the frame with interposed friction-rollers i, and slots u are cut through the front piece 8 to permit the moving up and down of the weights and the consequent raising and lowering of the shutters, as will be readily understood. By screwing up the thumb-screws qthe shutters may be locked at any point desired. The lower end of the ropes 71 after passing around the pulleys 1) have their upper ends secured, as at 1:, near the top ends ofthe slots u, as seen in Fig. (l, where one of the weights is shown at the upper end of its slot and with its shutter lowered.

The shutters, as seen in Fig. 7, need not have guide-ribs 7L, like the sash P, but may have simply top and bottom pins 10, projected into grooves a in the walls F, which pins are spring-projected and may be retracted to release the shutters when it is desired to remove them from the frame. Just outside of the shutters is a burglar-proof grating in a metallic frame T, Fig. 3, whose lower part is preferably an ornamental grille U, adapted to cover the upper sash P-that is to say, to register with the same when the grating is raised to its fullest extent and whose upper part is composed of vertical metal bars V. This grating is supported by cords or ropes 1), extending from each side up over pulleys, as at c, and thence down over pulleys, as at cl, Fig. 12, to a weight XV in the left-hand box E, Fig. 1.

The weights Q N for the upper sash and the burglar-proof grating are preferably constructed like the weights S for the shutters, and have outside knobs, as at 6, working through slots in the window-frame forraising and lowering the upper sash and the burglar: proof frame and for arresting the same at any point desired. The burglar-proof frame has in addition at its lower side, at each en.d,an arm X, Fig. 13, whose lower portion, slightly reduced, passes through a bossed perforation f in the sill C and is provided with a notch g, adapted to be engaged by a bolt h, which is springprojected in a casing t" and is withdrawn by a button j just beneath the sill O, the construction being such that when the burglarproof frame is lowered to itsfull extent its rods X will become automatically engaged and locked by the bolts h to prevent the raising of said frame from the outside, and the purpose of the boss-is to keep water out of said opening.

Just out-side of the burglar-proof frame and sliding in guides in the walls F are two screens Y Y, Figs. 2 and 10, which, can be operated by hand and normally remain down to close the window-opening in summer-time and can beraised up out of sight in the space-G in winter-time; It is to be observed that a partition-piece A is placed in the box or casing G and extends entirely across the same from the under side of the horizontal partition I to the top of the window-opening and that the upper small sash -P closes tight against the lower edge of this partition-piece A, and by this construction the passage of all air is excluded from the outside into the room, as will be readily understood.

The foregoing description embodies my improved window in its most complete form,

, though it is capable of modifications in some of its details to fit it for factory and office uses. In Figs. 8 and 9 I have shown a factory-win.- dow equipped with my invention and this, with the exceptions to be pointed out, is identical with the window-of Figs. 1 and 2. In this construction I employ three sashes, of which the upper sash P is the same as before, and also the sash L, except that between the bottom of the sash L and fitted in the same guides is a small sash B containing ground or opaque glass. The shutters in this case are of unequal length, the outer one B being the shorter and intended only to come to the bottom of the sash L and not to cover the sash B Also in this construction the screen or guard, instead of being a burglar-proof grating, is a wire'grating O of rather heavy wire in a single frame adapted to cover the entire window-opening and locked by the same bolts h with their knobs 3'', when the in hingingthe outerwalls s of the frame by'a screw or other suitablecatch at their lower ends when closed; This construction,

as seen in Fig. '2, permits 5 to be swung in to give access to the wells or weightboxes E when desired. As seen in Fig. 2, the weights Q andW might be left attached to the wall 3, or, if desired,- the thumb-screws q might be removed, leaving the weights hanging in the box or well, as will be readily understood.

While I have shown the wind ow-frames as constructed in tiers with the lower one meeting the next upper one, it is of course to be understood that this is not essential, for in buildings with very high ceilings there would be no necessity of extending the boxes G sufficiently high to meet the next superimposed window, as will be readily understood. Subject-matter shown and described in this application but not claimed is described and claimed in mysubsequent application, filed February 13, 1903, Serial No. 143,161.

Having thus fully described my invention, I claim'- '1. In window construction, the'combination of amain stationary frame, the glass-carrying sashes guided therein, a verticallysliding shutter guided in the frame outside of the glass carrying sashes, a verticallysliding screen or guard guided in said frame exterior of the sash and shutter frames, and a box or casing, within the wall and forming a contin uation of the window-frame, adapted to receive the main window-sash, the shutter and guard screens, when raised, substantially as described.

2. In window construction, the combination of a frame, the glass-carrying sashes guided therein, weights on one side of the frame for said sashes, vertically-sliding shutters guided in the frame outside of the glasscarrying sashes, hand-operated weights for said shutters, a vertically-sliding metal screen or guard 3.
